These cut, too.  There are vector operations and raster operations.  Raster
operations engrave, vector operations cut.

A 25W laser is more than enough for cutting acrylic of a sizable thickness.
Beyond this thickness, you have focusing problems that effect all lasers.

Cutting metal is not the best application for laser tools unless we spend
SERIOUS money.  Metal is hard for laser cutting because when metal melts, it
becomes very reflective.

As far as what brand to use, as much as I hate to sound the "Noone gets
fired for buying IBM" trumpet, I think it applies here.

There is a lease option that I would like to make people aware of.  It means
the equipment isn't ours, but it also means we don't have the large initial
investment, and we can get service as part of the contract.

But I don't want to spend decades talking about in on the list when we can
talk about this.  I'll even bring beer if it means avoiding YANBLFW.
